Display The Infiniband Fabric Topology - Oracle Exalogic Elastic Cloud Owner's Manual

Monitor the InfiniBand Fabric
mask control (LMC) for each switch. The output of the command is a mapping of
GUID to LID for switches in the fabric.
On any command-line interface (CLI), run the following command:
# ibswitches
The output is displayed, as in the following example:
Switch : 0x0021283a8389a0a0 ports 36 "Sun DCS 36 QDR switch localhost" enhancedport 0
lid 15 lmc 0
15.1.2 Identify All HCAs in the Fabric
You can use the ibhosts command to display identity information about the host
channel adapters (HCAs) in the InfiniBand fabric in a subnet. This command displays
the GUID and name for each HCA.
On the command-line interface (CLI), run the following command:
# ibhosts
The output is displayed, as in the following example:
Ca : 0x0003ba000100e388 ports 2 "nsn33-43 HCA-1"
Ca : 0x5080020000911310 ports 1 "nsn32-20 HCA-1"
Ca : 0x50800200008e532c ports 1 "ib-71 HCA-1"
Ca : 0x50800200008e5328 ports 1 "ib-70 HCA-1"
Ca : 0x50800200008296a4 ports 2 "ib-90 HCA-1"

15.1.3 Display the InfiniBand Fabric Topology

To understand the routing that happens within your InfiniBand fabric, the
ibnetdiscover command displays the node-to-node connectivity. The output of the
command is dependent upon the size of your fabric. You can also use this command to
display the LIDs of HCAs.
On the command-line interface (CLI), enter the following command:
# ibnetdiscover
The output is displayed, as in the following example:
# Topology file: generated on Sat Apr 13 22:28:55 2002
#
# Max of 1 hops discovered

Note:
The actual output for your InfiniBand fabric will differ from that in the
example.
Note:
The output in the example is just a portion of the full output and varies for
each InfiniBand topology.
